CAN-SOLDERING MACHINE.

SPECFICATIGN forming part of Letters Patent No. 588,808, dated August 24, 1897.

' Application led January 2, 1896. Serial No. 574,141.v (No model.)

To all whom, it rit/ny Pon/www" The object of my invention is to obtain av soldering-machine for cans, more especially for oval and long cans. The mechanism invented by me for this purpose is as illustrated in the accompanying drawings, in which- Figure l is a perspective plan View of my soldering-machine. Fig. 2 is a detail of a band-wheel and an inner end of a long arm, showing means for securing the wheel on the arm. Fig. 3 is a detail of a section of along arm, a hoop, and clips thereon for supporting the hoop on the arm. Fig. 4 is a crosssectional view of the device, taken on line fm, fn, Fig. l. Fig. 5 is a View similar to the latter, showing an apparatus for heating the soldering-trough underneath the same. Fig. 6 is a detail of two tracks and means for supporting the same.

The numerals and letters designate the parts of my machine'referred to in describ-- ing the same.

The circular bed-plate l-is rigidly mounted on some suitable frame and a furnace is provided under that section of such plate embraced within the letters X and Y. On the bed-plate is provided a trough extending from z to y, which is divided by a box-like partition, inserted at 2, into two compartments or baths, one, 3, for the acid solution and the other, 4, for the molten solder.

5 is a block or pillow in which the bandwheel 6 is j ourn aled The band-wheel is provided with a series of long arms 7, havingA antifriction-wheels S at their ends. These arms are threaded at their inner ends and are secured in apertures in the rim of the bandwheel by means of two nut-s 9r and 10, (see Fig. 2,) thus adapting such arms to be laterally adjusted to some degree.

l1 is a hoop which is supported from the arms 7 by means of suitable clips l2, which clips are also adapted to lateral adjustment, a detail of this construction being shown in Fig. 3. From such hoop 11 project a series of short or auxiliary arms 13, which are secured in the hoop by the same means as the arms 7 are seouredin the rim of the bandw'heel, and like the latter arms they are adapted to be laterally adjusted.

14- is a track rigidly xedin the acid-tray 3. 15 and 16 are two tracks supported on three arms 17, each of which is mounted on the bed-plate by means of two short posts 1S and 19, which posts are provided with two nuts -or collars 20, holding'the arms 17 between them, as seen in Fig. 4, and the base or lower ends of such posts 18 1H being threaded and inserted in threaded perforations in the bedplate, so as to be vertically adjustable.

21 is a bead extending along the interior of the outer wall of the troughs to prevent the edges of the can from binding against such outer walls. g Y Y The. rail or track 16 is covered with asbestos to offer some resistance to the cans and turn the same while being moved forward by the arms 7. v

22 is a rail supported on posts 23,- attached to the outer wall of the trough, this rail being provided for the cans to lean against while traveling around the machineiand dipping their edges inthe acid and the molten solder.

The operation of my machine is very simple. The shaft of the band-wheel 6 is re volved by means of suitable gearing, as indicated bythe arrows. The cans are fed tothe machine at A and are revolved and moved by the arms 7, in the first place through the acid-trough and next through the soldertrough, while so revolving leaning outward against the rail 22 and dipping their edges in the molten solder as they travel along and are finally ejected from the machine at B.

The short or auxiliary arms 13 are provided to keep long cans in position and causethem to revolve evenly. For the purpose of illustrating this operation one long can is shown in broken outlines L C in Fig. 1, and it will be observed that the auxiliary arm 13 holds the inner end of such long can in place by preventing the same from rolling away from .the arm 7.'

Underneath the solder-trou gh is suspended in dependingstraps Oa suitable tubular fluidheating device D, having apertures d in its upper surface, as shown in Fig. 5, for the IOO ignition of the iiuid in the tube for heating the soldertrough directly above the same.

l. In a soldering-machine, in combination, the circular bed-plate, rigidly mounted, a circular trough upon such bedplate, divided by a partition into the two compartments 8 and 4f; a suitable heating apparatus under the compartment 4 to heat the same; the wheel (l, lijournaled in a suitable pillow orsupport; means for revolving such wheel; the arms 7, secured in slots or apertures in the rim of the wheel 6, by means permitting such arms to be laterally adjusted, and suoli arms being provided with antifriction Wheels S at their free ends; ythe rigidly-f`1xed rail 14, and the rails 15 and 1G mounted ou suitable supports adapting the same to vertical adjustment; a suitable friction covering, for the purposes specified, on such rail 1G; a bead 2l, extending along the interior of the outer Wall of the troughs or compartments, and the rail 22 for cans to lean against, all substantially as set forth.

2. In a soldering-machine in combination, the circular bed-plate rigidly mounted, a circular trough upon such bed-plate, divided by a partition into the two compartments 3 and- 4; a suitable heating apparatus under the compartment 4 to heat the same; the wheel G journaled in a suitable pillow or support; means for revolving such Wheel; the arms 7, secured in slots or apertures in the rim of the wheel G by means permitting such arms to be laterally adjusted, and such arms being` provided with antifriotiomwheels 8 at their free ends; the hoop 11 supported from the arms 7 by adjustable clips, the auxiliary arms 13 secured in slots or apertures in the rim of such hoop ll by means permitting such arms to be laterally adj usted, and such arms 13 beinglikewise provided at their free ends with antifriction Wheels; the rigidly-fixed rail l-i and the rails 15 and. 16 mounted on suitable supports adapting the same to vertical adjustment; a suitable friction covering, for the purpose specified, on such rail 16; a bead 21 extending along the interior of the outer Wall of the troughs or compartments; and the rail 22 for cans to lean against, all substantially as set forth.

In witness whereof Iliave hereunto set my signature, in the presence of two Witnesses, this 27th day of November, 1895.
